The only issue I could see with them is that they would be too sharp and the recoil might sever the tubing which would drastically increase performance overtime. However, adding some material to reduce the catching of that edge can certainly be done.
In addition, clamping the tubing after a point where it has attained some friction is much better than to the final stretched position.

What Cory is getting at is make a capstan of sorts;

Wrap the surgical tubing a few times around something and the clamping force required afterwards is a fraction of the loaded tension.
